Application fi1ed. July 29,

To all whom it may concern:

Be it known that I, JEROME C. DIn'rnIoH, of the city of Gait, in the county of Water 100, in the Province of Gntario, Canada, have invented certain new and useful Improvements in Handsaws, of which the following is a specification.

This invention relates to hand saws, and more particularly to improvements in the hand saw described and claimed in Canadian Letters Patent No. 143,468, dated Oct. 15th, 1912.

In that patent there is shown and described means for protecting the handle from injury, comprising tangs projecting from the blade and lying in slots formed in the outer edges of the handle. Saw handles have also been reinforced by bolts extended longitudinally through the hand grips, but owing to the presence of the tangs, it has not been possible to use such reinforcing bolts with the saw shown in the above mentioned patent, though such re-inforcement is desirable. My object therefore is to devise means whereby both forms of reinforcement may be satisfactorily combined in the same handle.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which Figure 1 is a side elevation, partly in section, of part of a hand saw provided with my improvements; and

Fig. 2 a cross section on the line (1.(/. in Fig. 1. I

In the drawings like numerals of reference indicate corresponding parts in the different figures.

1 is a saw blade, and 2 a handle, which is of ordinary form and is provided with the v hand grip 3. The upper and lower edges of the handle are grooved to receive the rearwardly extending tangs 1, which are integral with the saw blade. The forward part of the handle is also grooved, as is usual, to receive the rearward part of the blade adjacent the tangs. The blade and handle are secured together by the usual bolts 5. The tangs, it will be noted, as in the prior patent hereinbefore Specification of Letters Patent.

Fatented Dec. 6, i921 1921. Serial No. 488,474.

referred to project slightly from the handle, and extend into and slightly beyond the ears 6 at the ends of the hand grip. The present invention concerns itself particularly with the means of reinforcing the end grip. For this purpose I provide the rod 7, which extends through a hole formed lengthwise of the hand grip, and intersecting the grooves formed in the upper and lower edges of the handle.

While this rod might terminate at the inner sides of the grooves, it is preferably extended at each end, andthese extended ends are slotted for the passage of the tangs 4. In assembling the saw, the rod is first placed in position in the handle, and the tangs then slipped into place and the blade and handle secured together by the bolts 5. The rod 7 is held from endwise motion by its engagement with the tangs, and serves to efficiently reinforce the hand grip.

What I claim as my invention is 1. In a hand saw, the combination of a blade provided with two rearwardly extending tangs; a handle having its upper and lower edges grooved to receive said tangs; and a reinforcing rod extending through the handle in the same plane as the blade and having notches formed in its ends through which the tangs extend.

2. In a hand saw, the combination of a blade provided with two re-arwardly extending tangs; a handle having its upper and lower edges grooved to receive said tangs; and a reinforcing rod extending through the handle in the same plane as the blade and held in place by said tangs.

3. In a hand saw, the combination of a handle provided with a hand grip, the upper and lower edges being grooved and a hole formed in the hand grip intersecting the said grooves; a saw blade provided with rearwardly extending tangs fitting into said grooves; and a reinforcing rod fitted in the hole in the hand grip and held in place by said tangs.

Signed at Galt, Canada, this 18th'day of July, 1921.
